EXECUTIVE SUMMARY (excerpt)


A two-year screening survey of contaminants in fish on the California coast was conducted in 2009 and 2010. This report presents new data from sampling that focused on the North and Central coasts in 2010. Five species were examined at each sampling location. The array of species selected for sampling included those known to accumulate high concentrations of contaminants and therefore serve as informative indicators of potential contamination problems. Contaminant concentrations in fish tissue were evaluated using thresholds developed by the California Office of Environmental Health Hazard Assessment (OEHHA) for methylmercury, PCBs, dieldrin, DDTs, chlordanes, and selenium, and a U.S. Environmental Protection Agency threshold for methylmercury that is being used by the State Water Resources Control Board to identify impaired water bodies.
